Girard, Patrick (author), Cheng, Yuanqing (author), Virazel, Arnaud (author), Zhao, Weisheng (author), Bishnoi, R.K. (author), Tahoori, Mehdi B. (author)Memories occupy most of the silicon area in nowadays' system-on-chips and contribute to a significant part of system power consumption. Though widely used, nonvolatile Flash memories still suffer from several drawbacks. Magnetic random access memories (MRAMs) have the potential to mitigate most of the Flash shortcomings. Moreover, it is...review 2020

Peters, D.J. (author)This report studies clamping phenomena in placed revetments on the Dutch dikes. One of the reasons of placing stones is that the stability of the single stones increases. Pull–out tests on single stones show a strength up to 10 times the single stone weight. In present standardized design methods for placed revetments there is no significant...report 2003

Waarts, P. (author), Vrouwenvelder, A. (author)In most text books on Plasticity Theory a reference is made to the famous tests performed by Stiissi and Kollbrunner in 1935. The test object was a continuous beam on four supports, loaded by a concentrated point load halfway the central span. According to a straight forward application of the theory of plasticity the load carrying capacity of...journal article 1997

Van der Kooij, H. (author), Campbell, A.D. (author), Carpenter, M.G. (author)The different measures used to characterize postural sway are sensitive to variations in sampling duration, yet there remains marked variability and a lack of consistency in this temporal parameter when compared between studies. We investigated the effect of sampling duration on 22 commonly used frequency and time domain measures and stabilogram...journal article 2011

Janic, M. (author)This paper develops an analytical model for the assessment of the cost performance of a given logistics network operating under regular and irregular (disruptive) conditions. In addition, the paper aims to carry out a sensitivity analysis of this cost with respect to changes of the most influencing factors. In particular, this is expected to...journal article 2009

Kooiman, A.G. (author), Walraven, C. (author)With the increasing number of applications in practice, the demand for standardised test methods and design rules for Steel Fibre Reinforced Concrete (SFRC) arises. Test methods need to be practical, which means that they have to be relatively cheap and simple to carry out. Design models should be easy to use and reliable. This paper presents a...journal article 2000

Steenbergen, R.D.J.M. (author), Vrouwenvelder, A.C.W.M. (author)Evaluating and upgrading existing structures becomes more and more important. For a large part of the existing infrastructure and buildings the design life has been reached or will be reached in the near future. These structures need to be reassessed in order to find out whether the safety requirements are met. Not only for new structures but...journal article 2010

Maljaars, J. (author), Steenbergen, R. (author), Abspoel, L. (author), Kolstein, M.H. (author)The assessment of the structural safety of existing br idges and viaducts becomes increasingly important in many countries owing to an increase in traffic loads. Most existing standards, however, are developed for the design of new structures. For this reason, an assessment method for determining the actual safety level of highway bridges and...journal article 2012
